  • Oven

    A reliable oven that can maintain a steady temperature is crucial. Preheat it to 374F (190C) for this recipe.


Step 1

Step 1: Preheat your oven
Preheat your oven to 374°F (190°C). This ensures the oven is hot enough when the cake layers are ready to be baked.Don't forget to preheat - it makes your baking more consistent!

Step 2

Step 2: Prepare the egg mixture
In a large bowl, whip the eggs with the sugar until the mixture is pale and fluffy.Use a hand mixer or stand mixer for best results.

Step 3

Step 3: Combine the dry ingredients
Add the baking soda slaked with lemon juice or vinegar to the egg mixture. Gradually add the sour cream and sifted flour, mixing well after each addition. Divide the mixture into two equal parts.Mix just until combined to avoid overworking the flour.

Step 4

Step 4: Add cocoa
Add the cocoa powder to one half of the batter and mix until well combined.Ensure no lumps of cocoa for an even chocolate flavor.

Step 5

Step 5: Bake the layers
Pour each batter half into a separate cake ring or pan. Bake in the preheated oven for 30 minutes or until a toothpick inserted into the center comes out clean. Allow the cake layers to cool completely.Don't open the oven door early; it can cause the cakes to sink.

Step 6

Step 6: Prepare the layers for assembly
Once cooled, cut off the tops of the cake layers to create a flat surface, then cut each layer in half horizontally. Use the tops for biscuit crumbs later.Use a serrated knife for the best cuts.

Step 7

Step 7: Prepare the gelatin
Soak the gelatin in water (ratio 1:6). Melt it slowly and allow it to cool, being careful not to let it harden.Melt the gelatin over low heat to avoid clumping.

Step 8

Step 8: Make the cream
Pour the cooled gelatin into the sour cream, and whip together with the sugar and vanillin until fluffy.Chill your mixing bowl for better whipping results.

Step 9

Step 9: Assemble the cake
Spread the cream generously over each cake layer and stack them. Cover the entire cake with a thin layer of cream.Apply cream evenly to avoid the cake tilting.

Step 10

Step 10: Finish the cake
Sprinkle the top and sides of the cake with the cake crumbs prepared earlier. Chill the cake for at least a couple of hours before serving.Chilling helps the flavors blend and makes slicing easier.
